it's what makes a subaru, a subaru. >>> welcome back to "starting point," everyone. we are live in boston. john berman here along with chris cuomo. the aftermath of the attacks on the boston marathon. really the crime scene is right behind us. we see police there. you see the medical tent there. that is where so many of the victims were treated right after the race. and then just on the other side of that street, still blocked off, a crime scene right now. boylston street the finish line. investigators right now going inch by inch on that street trying to find anything and everything they can. >> a local authorities say it's the most complex crime scene they've ever dealt with. and that means something here. this is a major city. they do a lot of types of criminal investigation. one of the reasons is because of logistics. the other is there's so much manpower on the ground they need a place to coordinate. just to give a sense of dimensions. 30 government agencies involved and boston's finest here, every day, 12-hour shifts. couldn't be more of an intense effort. that
